Coal mine machinery roller disassembling device

Coal mine machinery roller disassembling device - 2020 06 - 04 at present, in various coal mine machinery, the drum is a kind of common components, such as a large application of transmission belt, winch, etc. For all kinds of methods of roller disassembling axis is all use hammer hard hit shaft head, a little will exit from the bearing axis to pack or, do the shortcomings of a few: 1, not easy to operate, the worker labor intensity is high, the efficiency is low; 2, is fixed, safety coefficient is low; 3, it is easy to cause deformation and cracking on both ends of the shaft, also easy to cause shaft bending deformation. In order to solve the installation of the roller and remove the existing in the low efficiency, uneasy congruent technology problem and invented the coal mine machinery roller disassembling device. This device is implemented by the following technical scheme, structure including the big frame, in a big plane with roller, a guide in the side of the big frame, guide seat is equipped with side top one thousand jins, is at the top of the big rack is equipped with pressure roller one thousand jins, see the appended drawings. This device is mainly used for belt conveyor roller and a variety of small removal and installation of the hoist roller, the specific process is as follows: 1, drum, wrapped inside the drum tower, a fixed after putting it in a big plane inside; 2, depending on the location of the drum shaft, adjust the height of the top one thousand catties, with the need of disassembly and assembly axis direction, and guide the side of the top one thousand jins fixed; 3, pressure roller one thousand jins reaches down, inside the cylinder pressure big, to ensure that at the top of the side one thousand jins gesture, roller will not produce displacement, avoid because of side top one thousand jins and shaft alignment is not enough leads to the unexpected circumstances of roller rolling; 4, determined to fixed firmly, the side of the top one thousand jins, the shaft top entry or ejection cylinder. Diagram 1 drum disassembling device. Guide; 2. Large frame; 3. Pressure roller one thousand jin; 4. Drum; 5. Drum; 6. Axis; 7. Side top one thousand jins compared with the existing technology, the utility model in view of the difficult maintenance drum disassembling axis, through the design of the large frame drum of a set of fixed and dismantling of jack shaft, shaft by one thousand kg instead of human the disassembly and installation, improve the working efficiency, safety and quality of installation.
